Maria works in a hardware store. A bin of aluminum nails and a bin of iron nails are knocked over, and the nails get mixed up. Both sets of nails are the same color and size.

Use a magnet to separate the nails: iron is attracted to a magnet, while aluminum is not. The iron nails will stick to the magnet, leaving the aluminum nails behind, so the correct choice is “Iron is magnetic, and aluminum is non-magnetic.”
